Really enthusiastic when I hear about DSound, the very optimistic SoundCloud destroyer. 
My issue here is that for the past 2 months, I haven't been able to upload a single track to it. No progression on the loading bar, no nothing. It just stagnates for ages until I get bored of it and give up. 
I've tried Wav and mp3, different tracks of different lengths, but nothing... Can you guys work on that? You're talking about 5000+ users posting music on a daily basis, but maybe the biggest factor to slowing this down is how many other users struggle like me (and I'm good with technology)..
